Is there a wipeout tool for FAT32? (Users)

posted by fritz.mueller Homepage, Munich, Germany, 03.07.2024, 13:37

Hi,
I just wanted to know if there is a working wipeout tool for FAT32 that wipes the whole free parts of a FAT32 partition (2 TB).
As an alternative: Is there a working wipeout tool that wipes a WHOLE 2 TB HD including the MBR?

The reason:
I ran some tests (for time reasons only on a 30 GB virtual HD), filled it up with trash files and then deleted them so that the HD was "empty" again. So I could see if the programs really wiped with a hex editor.
Then I ran 3 different tools:
Wipefree from Uwe Sieber (https://www.uwe-sieber.de/util.html), it says that it should do 2 TB in about 55 hours, but the result was that I got less than 2GB. Additionally it only shows the amount of wiped size when you exit the program. It ran and ran over hours but only less than 2 GB were done when I aborted. Source Code is included but I saw nothing about the license.

Zerofill from Nikkho (https://sourceforge.net/projects/nikkhokkho/files/ZEROFILL/) 1.09 only wipes 2 GB (4x500 MB), but has a UI. It is the wiper delivered with FD.

The third tool that I tested was not free, created in about 1040 (!!) 100 MB files , but then it crashed as it had a unlucky filename tempxxxx.0 till tempxxxx.999 - so it fell out of 8.3 an ended in reality at .999 and in about 100 GB.

So all programs are far away from wiping a 2 TB HD.
